IFRS 16 (international) and ASC 842 (US GAAP) were designed in parallel and share the same core principle: leases go on the balance sheet. But the two standards diverge in several important ways — some minor, some significant enough to change how you structure leases and present results.
This guide is one part of the complete ASC 842 lease accounting guide, which covers scope, classification, measurement, entries, modifications, and disclosure end to end.
Here’s a practical side-by-side breakdown.
The Big Picture: What’s the Same
Before the differences, what’s aligned:
- Both require a right-of-use (ROU) asset and lease liability for most leases at commencement
- Both use present value of future payments discounted at the appropriate rate
- Both have a short-term exemption (≤12 months)
- Both apply to lessees — lessor accounting differs more significantly but is less commonly impacted
- Both require disclosure of maturity analysis, weighted-average rates, and future lease obligations
Difference 1: Lease Classification
This is the biggest practical difference.
ASC 842 (US GAAP)
Leases are classified as either operating or finance based on five classification tests:
- Transfer of ownership by end of lease
- Purchase option the lessee is reasonably certain to exercise
- Lease term is for the major part of the asset’s remaining economic life (typically ≥75%)
- Present value of payments is substantially all of the asset’s fair value (typically ≥90%)
- Asset is specialized with no alternative use to the lessor
If any criterion is met → finance lease. Otherwise → operating lease.
IFRS 16
IFRS 16 does not distinguish between operating and finance leases for lessees. All leases (above the thresholds) are treated like finance leases: depreciation + interest, front-loaded expense, financing cash flow for principal.
Why it matters
Under US GAAP, a company with mostly operating leases reports a single flat lease expense line — straightforward, non-volatile. Under IFRS 16, that same company reports depreciation + interest — EBITDA goes up, but profit is front-loaded in early lease years.
Difference 2: Discount Rate
ASC 842
Use the rate implicit in the lease if readily determinable. If not (usually the case), use the incremental borrowing rate (IBR). Private companies have a practical expedient to use the risk-free rate instead of the IBR.
IFRS 16
Same hierarchy: implicit rate first, then IBR. No risk-free rate option for private companies.
Difference 3: Short-Term and Low-Value Exemptions
ASC 842
One exemption: short-term leases (term of 12 months or less at commencement). Election is made by class of underlying asset. No low-value exemption.
IFRS 16
Two exemptions:
- Short-term leases — same as ASC 842, ≤12 months
- Low-value asset leases — assets with a value when new of approximately $5,000 USD or less. Election is lease-by-lease.
Difference 4: Income Statement Presentation
ASC 842
| Lease type | P&L presentation |
|---|---|
| Operating | Single lease expense line, straight-line |
| Finance | Depreciation (straight-line) + Interest expense (effective interest) |
IFRS 16
Since all leases are treated as finance leases: Depreciation of the ROU asset + Interest expense on the lease liability. Total expense is front-loaded for every lease.
Difference 5: Cash Flow Classification
ASC 842
| Payment type | Cash flow classification |
|---|---|
| Operating lease payments | Operating activities |
| Finance lease — principal | Financing activities |
| Finance lease — interest | Operating activities (or financing if policy election) |
IFRS 16
| Payment type | Cash flow classification |
|---|---|
| Lease liability — principal | Financing activities |
| Lease liability — interest | Operating or financing (policy choice) |
| Short-term / low-value | Operating activities |
Side-by-Side Summary
| ASC 842 (US GAAP) | IFRS 16 | |
|---|---|---|
| Lessee classification | Operating or Finance | Single model (all “finance-like”) |
| Short-term exemption | ≤12 months, by asset class | ≤12 months, by asset class |
| Low-value exemption | None | ~$5,000 USD, lease-by-lease |
| Discount rate | IBR (or risk-free for private) | IBR |
| Operating lease P&L | Single flat expense | N/A — all depreciation + interest |
| Finance lease P&L | Depreciation + interest | Depreciation + interest |
| Operating lease cash flow | Operating activities | Financing (principal) |
| Effective date | 2019 (public), 2022 (private) | 2019 |
Frequently Asked Questions
What is the main difference between IFRS 16 and ASC 842? Classification. ASC 842 keeps the operating-versus-finance lease distinction for lessees; IFRS 16 uses a single model where lessees treat almost all leases like finance leases — depreciation plus interest, with front-loaded expense.
Does IFRS 16 have operating leases? Not for lessees. IFRS 16 eliminated the operating/finance distinction on the lessee side — every in-scope lease is recognized with an ROU asset and lease liability and expensed as depreciation plus interest. Lessor accounting still distinguishes the two.
Does IFRS 16 have a low-value lease exemption? Yes. IFRS 16 exempts leases of low-value assets (roughly $5,000 or less when new), elected lease-by-lease, in addition to the short-term (12 months or less) exemption. ASC 842 has only the short-term exemption.
Can one Excel workbook handle both ASC 842 and IFRS 16? Largely yes. The underlying math — present value of payments, amortization waterfall, ROU rollforward — is identical. The difference is presentation: under IFRS 16 you treat every lease like a finance lease and skip the operating-lease split.
Building the Schedule
Whether you’re under ASC 842, IFRS 16, or both, the underlying math — PV of payments, amortization waterfall, ROU asset rollforward — is the same. The difference is in presentation and classification.
If you need the period-by-period entries, see ASC 842 Journal Entries: A Complete Guide with Examples — the operating-lease split applies only under US GAAP; under IFRS 16, treat every lease like a finance lease and skip the operating-lease section.
The ASC 842 Lease Accounting Workbook is structured around US GAAP but the amortization math and journal entry logic is compatible with IFRS 16 as well.
